Description

Technical Field

[0001] This utility model relates to the field of coal preparation equipment technology, and in particular to a heavy medium separator for coal preparation. Background Technology

[0002] Heavy media refers to media with a density greater than 1 g / cm3, including heavy suspensions and heavy liquids. Heavy media separation is a separation process carried out in media with a density greater than that of water. It can be used in coal preparation operations and is widely used in the coal preparation field. Furthermore, heavy media liquid separation is an important operational step in coal preparation.

[0003] Currently, when sorting materials, a water impeller is installed at the bottom of the material inlet to move the material toward the collection end. During this process, the pushing speed is slow in order to avoid affecting the sinking and floating. However, in actual use, the mobile feeding method is still affected by the fluctuation of the medium liquid, which leads to the problem of the sorting being affected.

[0004] Therefore, it is necessary to provide a heavy medium separator for coal preparation to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a heavy medium separator for coal preparation to solve the problem that the existing device, in actual use, is still affected by the fluctuation of the medium liquid when using a mobile feeding method, which leads to the impact on the separation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A heavy media separator for coal preparation includes: a working box, a regulating box, a processing box, and a drain pipe;

[0008] The working box is an inverted trapezoidal structure, with the distance between the top two sides being greater than the distance between the bottom two sides. The bottom of the working box is connected to the adjustment box, which is a rectangular structure. A processing box is installed at the bottom of the adjustment box and is connected to it. Support legs are installed at the bottom of the processing box. Heavy medium liquid is pre-filled inside the working box.

[0009] In one embodiment, the inner bottom surface of the treatment tank is a concave surface converging towards the center, a drain pipe is installed at the center of the concave surface, the drain pipe is connected to an external liquid collection device, the drain pipe has a built-in solenoid valve, and a metal filter screen is installed at the connection between the drain pipe and the treatment tank.

[0010] In one embodiment, a material handling door is installed on the front end face of the processing box, and a sealing strip is installed between the material handling door and the processing box.

[0011] In one embodiment, a mounting frame is installed in the middle of the top surface of the working box. A hydraulic rod is installed on the top of the mounting frame. The bottom of the hydraulic rod passes through the mounting frame and is connected to the top of an adjusting rod. The bottom of the adjusting rod is connected to the top of a blocking block. The blocking block is a frustum-shaped structure and is located on the inner bottom surface of a limiting plate. The bottom width of the blocking block is greater than the bottom opening size of the limiting plate. The limiting plate is an inverted funnel shape with both its top and bottom surfaces being open. The limiting plate and the blocking block are both located inside the adjusting box, and drainage holes are provided on the surfaces of both the limiting plate and the blocking block.

[0012] In one embodiment, a gap is left between the inner bottom surface of the mounting bracket and the top surface of the working box, and an operating gap is left between the bottom end of the hydraulic rod and the top liquid surface of the working box. The adjusting rod, the limiting plate, and the plug are all treated with wear-resistant and corrosion-resistant materials.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) This utility model puts the work material into the working box and soaks the work material for a period of time. The upper layer of material floats on the top of the working box, and the lower layer of material sinks into the processing box through the adjustment box. This allows the whole device to keep the material in a soaking state without moving it, and wait for separation.

[0015] (2) In this utility model, after the material is soaked in the overall device for a period of time, the lower layer material enters the processing box through the bottom opening of the limiting plate. When it is necessary to collect the upper and lower layers of material, the hydraulic rod is activated to drive the adjusting rod to rise, and at the same time, the blocking block rises to block the bottom opening of the limiting plate, thus separating the upper and lower layers of material. The drain pipe is opened to discharge the medium liquid in the device, and then the upper layer material falls into the limiting plate. By opening the material retrieval door, the lower layer material is taken out first. After completion, the hydraulic rod is activated to drive the adjusting rod and the blocking block to descend, so that the upper layer material falls into the processing box below at the inclined surface of the limiting plate, and the lower layer material is collected, thus completing the sorting operation.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0021] like Figures 1-2 As shown, the present invention provides a heavy medium separator for coal preparation, comprising: a working box 1, an adjusting box 2, a processing box 3, and a drain pipe 4;

[0022] like Figures 1-2 As shown, the working box 1 is an inverted trapezoidal structure, with the distance between the top two sides being greater than the distance between the bottom two sides. The bottom of the working box 1 is connected to the regulating box 2, which is a rectangular structure. A processing box 3 connected to the bottom of the regulating box 2 is installed therewith, and support legs are installed at the bottom of the processing box 3. The working box 1 is pre-filled with a heavy medium liquid. During operation, the working material is put into the working box 1 and soaked for a period of time. The upper layer of material floats on the top of the working box 1, while the lower layer of material sinks into the processing box 3 through the regulating box 2. This allows the entire device to maintain the soaking state without moving the material, waiting for separation.

[0023] Preferably, in one embodiment, such as Figures 1-2 As shown, the inner bottom surface of the treatment tank 3 is a concave surface that converges towards the center. A drain pipe 4 is installed at the center of the concave surface. The drain pipe 4 is connected to an external liquid collection device. A solenoid valve is built into the drain pipe 4. A metal filter screen is installed at the connection between the drain pipe 4 and the treatment tank 3.

[0024] Preferably, in one embodiment, a material receiving door 31 is installed on the front end face of the processing box 3, and a sealing strip is installed between the material receiving door 31 and the processing box 3. The material separated inside the processing box 3 is collected and processed by opening the material receiving door 31.

[0025] Preferably, in one embodiment, a mounting frame 5 is mounted on the middle section of the top surface of the working box 1. A hydraulic rod 51 is mounted on the top of the mounting frame 5. The bottom of the hydraulic rod 51 passes through the mounting frame 5 and is connected to the top of the adjusting rod 52. The bottom of the adjusting rod 52 is connected to the top of the blocking block 54. The blocking block 54 is a frustum-shaped structure and is located on the inner bottom surface of the limiting plate 53. The bottom width of the blocking block 54 is greater than the bottom opening size of the limiting plate 53. The limiting plate 53 is an inverted funnel shape with open top and bottom surfaces. The limiting plate 53 and the blocking block 54 are both located inside the adjusting box 2. Drainage holes 55 are provided on the surfaces of the limiting plate 53 and the blocking block 54 during operation. After the material is soaked in the overall device for a period of time, the lower layer material enters the processing box 3 through the bottom opening of the limiting plate 53. When it is necessary to collect the upper and lower layers of material, the hydraulic rod 51 is activated to drive the adjusting rod 52 to rise, and simultaneously drive the blocking block 54 to rise to block the bottom opening of the limiting plate 53, thus separating the upper and lower layers of material. The drain pipe 4 is opened to discharge the medium liquid in the device, and then the upper layer material falls into the limiting plate 53. By opening the material picking door 31, the lower layer material is taken out first. After completion, the hydraulic rod 51 is activated to drive the adjusting rod 52 and the blocking block 54 to descend, so that the upper layer material falls into the processing box 3 below at the inclined surface of the limiting plate 53, and the lower layer material is collected, thus completing the sorting operation.

[0026] Preferably, in one embodiment, a gap is left between the inner bottom surface of the mounting bracket 5 and the top surface of the working box 1, an operating gap is left between the bottom end of the hydraulic rod 51 and the top liquid surface of the working box 1, and the adjusting rod 52, the limiting plate 53, and the blocking block 54 are all treated with wear-resistant and corrosion-resistant materials.

[0027] Working principle of this utility model:

[0028] During operation, materials are fed into the working chamber 1 and soaked for a period of time. The upper layer of material floats on top of the working chamber 1, while the lower layer sinks into the processing chamber 3 via the regulating chamber 2. This allows the entire device to remain soaked without moving the materials, waiting for separation. After soaking for a period of time, the lower layer enters the processing chamber 3 through the bottom opening of the limiting plate 53. When it is necessary to collect the upper and lower layers, the hydraulic rod 51 is activated to raise the regulating rod 52, simultaneously raising the blocking block 54 to block the bottom opening of the limiting plate 53, thus separating the upper and lower layers. The drain pipe 4 is opened to discharge the liquid medium in the device, allowing the upper layer to fall into the limiting plate 53. The material is then removed by opening the material retrieval door 31. After this, the hydraulic rod 51 is activated to lower the regulating rod 52 and the blocking block 54, allowing the upper layer to fall into the processing chamber 3 below at the inclined surface of the limiting plate 53, thus collecting the lower layer and completing the sorting operation.

[0029] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
